ENOCH GOOLNIK, OF MILE END, LONDON, ENGLAND.

APPARATUS FOR GRINDING AND SHAEPENING RAZORS, KNIVES, AND THE LIKE.

To all'whom it may concern:

I Be it known that I, ENoon' GooLNIn, residing at 1 Tredegar Square,Mile End, London, England, have invented certain new and usefulImprovements in Apparatus for Grinding and Sharpening Razors, Knives,and the like; and I do hereby declare the following to be a full, clear,and

V ping operation may be accomplished in an easy and convenient manner.

To this .end the invention consists in a pair'or pairs of'suitablerollers spaced apart and adapted to be continuously rotated andsimultaneously slid backward and forward, the razor or knife being heldin a carrier device between the rollers, said carrier device beingintermittently actuated in such manner that the razor or other articleis caused to bear first upon one of the said rollers formingthe pair andthen upon the other.

The carrier device in which the razor or the like is held duringtreatment is adapted toalways cause the razor or the like to bearagainst the rollers with a resilient or elastic pressure, and means areprovided for easily obtaining the exact adjustment of the razor oiflthelike with regard to the rollers.

The accompanying drawings illustrate by way of example a machine made inaccordance with the invention adapted for use for grind ng and stroppingrazors.

I'- igure 1 is a part sectional side elevation of the complete machine;Fig. 2 is a side elevation from the right of Fig. 1, certain parts beingremoved for elearness; Fig. 3 is a sectional elevation on line A;-i3 ofFig. 1; Fig. "l is a part plan of Fig. 1; Figs. 5 and 6 are detailsshowing respectively an end view of the razor holder, and the post tionsof the razor blade with respect to the grinding rolls; Figs. '7 and 8are respectively front elevation and side elevation of a modification,and, Figs. 9 and 10 are details of further modifications.

the apparatus comprises a framing consisting of two spaced plates (1 aconnected by distance bolts 0 and mounted upon a suit able base 11.Slidably and rotatablymounted in these two plates are a pair ofhorizontal rods 0 0 arranged parallel to each other the ends of whichrods are provided with rollers d d and e 6 respectively, those d dhaving a leather covered surface for the purpose of stropping, whilethose 6 6 may be composed of any suitable grinding inledia, such asemery, carborundum or the The rods 0 c are coupled together by gear Y 7,one of which meshes with a gear wheel 2 adapted to be driven to rotateboth f and f in opposite directions, from the hand wheel 9 through shaftg and interposed gear wheels f f and f he pairs of rollers d, e, inaddition to be- .ing rotated as described, are also caused to 'besimultaneously slid to and fro axially. For this purpose a lever Ii. ispivotally mounted to one side of the machine at h the upper torked endof which engages with a cross bar 0" carried by the rods 0 0 and thelower forked ends of said lever it engage" w th pins mounted upon across-head 2' which 18 freely mounted by a pin and slot connection 2'upon the endof a pivoted ra; At the lower side of this rod is provided apin or friction roller 9" adapted to co-act with a cam groove is formedin a drum is, which cam groove is so formed as to impart a to and fromovement to the pin when rotated by the handwheel g.

The rods 0 c carrying the stroppiiig and grinding rollers are formedwith feathers c to allow of the combined rotary and sliding movementthereof.

The razors or other implen'ients to be operated upon are carried inholding devices slmwn at X at each side of the machine as in Fig. l, andin side view and plan in Figs. 5 and 4. Each of those holding de- Thebars n are hingedly mounted about a vertical pivot n at each end of arock shaft 79 disposed centrally above the rods 0 0 and said bars areadjustable about said pivots by means of a screw 0 one end of which isrevolubly mounted in a pivoted bush 0 on a bracket or arm 32 while theother end of said screw works in a pivoted nut 0 on the bar 11.

9 indicates in dotted lines the razor in position for operation the edgeof which it will be noticed is just above the centers of the rollers d eand by means of the adjusting screws m and 0 the position of the razoror other implement both as regards height and alinement can be easilyand exactly obtained.

The shaft p is adapted to be rocked intermittently so as to move therazor or knife at the end of each sliding movement of the rollers, d e,from engagement with one roller of the pair to the other; this is shownin Fig. 6 where the full line 9 indicates the position of the razorwhile the rollers are sliding axially in one direction, and the dottedline Q2 when moving in the opposite direction.

The rocking movement imparted by the shaft 7) to the part 1 is greaterthan that of the actual movement of the razor or knife blade and thus byreason of the springs m said blade is kept in contact with therespective rollers by a yielding or resilient pressure.

The shaft p is intermittently rocked by means of a cam 1' mounted on thedriving shaft 9 of the apparatus, spring pressed lever s with frictionroller 8, link 8 and arm .9 The cam r is formed with two concentricportions of different radius whereby the rock shaft 7) and carriers Xare held stationary' in one position or the other during the slidingmovement of the stropping and grinding rollers.

In' use the razors to be ground or stropped are clamped in the holders,adjusted if required in regard to the rollers and the handle turnedsmartly whereupon the rollers are rotated and slid along each side edgealternately which combined action together with the resilient pressurequickly and efficiently effects the desired end.

The apparatus, of course, may, instead of being driven by hand, beoperated from a .suitable motor or in other desired way.

It will be understood that any other suitable mechanism for obtainingthe differentmotions may be employed instead of that described. Forinstance, Figs. 7 and 8 show a modified method of imparting theintermittent side movement to the holders. In the construction the bar;0 is not rocked as in the previous construction but is adapted to heslid first to one side and then to the other by means of a pivoted leverif having -holdcr carried by the a slotted or forked end at for engagingthe shaft 3) while the lower end is actuated by the cam r similarly tothe first described arrangement. In order to insure the bar p beingmaintained in proper axial position during its movement, a pair oftoothed racks u are fixedly mounted upon the said bar adapted to co actwith a pair of pinions u carried upon a counter shaft u revolublymounted in the frames a a whereby the transverse travel of the bar 2 isuniform. The bar ,1) is provided with guide blocks 1 sliding in slots orguideways p in t e frames which allows of the sliding movement andprevents the bar from turning.

Fig. 9 shows a modification of the first de scribed arrangement forimparting the rocking movement to the bar p. In this form theintermediate levers s s are dispensed with and a disk 0 having a camgroove "0 formed in its face is adapted to intermittently actuate thebar 19 through arm '0 and roller 11 direct. The said cam disk '0 isdriven in any suitable manner as, for instance, as shown, from the gearwheel f by wheel 2:.

Fig. 10 shows a modified method of imparting the sliding movement to therods 0 0 In this form the cam r is dispensed with and the lower end ofthe lever h is coupled by an arm to to an extension :12 mounted upon ashaft y and driven through bevel gearing z.

By a further modification of the last construction the rods 0 0 could becoupled direct to a suitably driven crank by means of a connecting rod.

Having now particularly described and ascertained the nature of my Saidinvention and in what manner the same is to be per formed, I declarethat what I claim is 1. In a grinding machine, the combination, with asupporting frame, and a blade rame; of two shafts journaled in the frameand provided with sharpening rollers, driving mechanism for revolvingthe said shafts in opposite directions, a cam also revolved by the saiddriving mechanism, a radius-rod pivoted at one end to the frame andhaving a projectlon at its free end which engages with the said cam, acrosshead pivoted to the said radius-rod, and a lever pivoted to theframe and having its opposite ends operatively connected with the saidshafts and with the said crosshead and operating to slide the saidrollers longitudinally.

2.
